New Membrane Removes Nearly 100% of Ammonia From Wastewater in Minutes

A new electrically powered filter can strip nearly all ammonia nitrogen from wastewater in just over a minute while also breaking down carbon-based pollution.

Researchers have developed an electro-filtration process that uses chlorine oxide radicals (·ClO) generated inside a specialized membrane to remove nitrogen and organic contaminants simultaneously. Reported in Engineering, the technology could provide a faster and more efficient way to treat complex wastewater without adding chemical precursors.

Wastewater treatment plants often rely on separate biological, chemical, and physical steps to control different pollutants. Ammonia can damage aquatic ecosystems by consuming oxygen and promoting excessive algal growth, while organic contaminants contribute to the chemical oxygen demand (COD) of discharged water.

Computer Scientist Pushes a 1996 Algorithm Beyond Its Longstanding Limit

A new algorithm solves a blind spot that has challenged computer scientists since 1996, improving distance estimates for nearby points in massive networks.

Navigation apps usually solve one route at a time, such as finding the fastest way from a hotel to an airport. Computer scientists face a far larger version of that challenge: calculating the shortest distance between every possible pair of locations in a network.

Known as the All-Pairs Shortest Paths (APSP) problem, this task applies to far more than road maps. A graph can represent computers connected by data links, stations joined by rail lines, proteins interacting inside a cell, or neurons communicating in the brain. The points are called vertices, and the connections between them are edges.

Google Gemini Broke Into Real Company Systems After Security Test Domain Mix-Up

Google’s Gemini model has become the latest artificial intelligence (AI) system to access the internet and break into other companies during a cybersecurity evaluation. The development was first reported by The Wall Street Journal.

The incidents occurred in May 2026 as part of a test run conducted by Israeli company Irregular. The evaluation partner was also involved in similar hacks disclosed by OpenAI, Anthropic, and Meta.

According to the Journal, the model gained access to a protected system after repeatedly guessing its password. Two other cases related to the model finding credentials in a public repository, allowing it to obtain unauthorized access to protected systems.

Fake LastPass Authenticator GitHub repos push new Rapuncel infostealer

An ongoing malware campaign uses SEO-optimized GitHub repositories to impersonate well-known software firms to push a previously undocumented information stealer called Rapuncel.

LastPass and Delphos Labs uncovered the campaign, which they report impersonates the password manager brand and at least 39 other companies.

Alongside the Rapuncel infostealer, the repositories deliver a Microsoft-signed kernel driver that can disable 145 antivirus and endpoint detection and response (EDR) products.

Microsoft Teams will let admins block custom file extensions

Microsoft Teams will soon let administrators tweak the list of file extensions commonly associated with malware and security threats to meet their company’s security requirements.

This will come as an update to Weaponizable File Protection, a built-in Teams messaging safety feature that scans conversations and blocks chat or channel messages with dangerous, high-risk file attachments.

As detailed in a new Microsoft 365 roadmap entry, the feature is currently in development and will start rolling out in November 2026.
